Major patent expiration could spark a second 3D printing revolution | ExtremeTech.

SLS machines user a high-powered laser to fuse small particles of material, released almost as an aerosol, to the growing object. With this technology it is possible to print plastic, metal, ceramic, or glass — virtually anything that can be released as a powder and heat-fused to a growing print. If this technology comes down in price even a fraction as far as FDM has, the at-home 3D printing revolution could finally begin in earnest.

I am wondering who will be the first to list a SLS 3D printer on Kickstarter. The hack/maker versions I bet are on their way.

Below is a video of the SLS printing process and the finishing process. The finishing process produces some waste and you need to wear protective gear.
